I am simply suggesting that you have not directly addressed your addiction via any formal type of sobriety plan. There are many - a short list below
1. Meeting based Recovery ( AA, LifeRing, Celebrate Recovery, Etc )
2. Counseling ( addiction specific or general )
3. Rehab - ( inpatient or outpatient )
4. Self-based recovery ( AVRT, etc )
5. Addiction books and literature
6. Online recovery ( SR ) - Chat meetings, monthly threads, etc
There are more and you can use multiple. You mentioned yourself that you need accountability - that has to come from within, but any of the above will allow you access to accountability specific to addiction.
Exercise and eating well are good for you physically, but they don't address your addiction.
